8 Claims.

This invention relates to window frame and sash constructions, particularly constructions which are especially adapted for motorvehicles, railway cars etc., and has for its object, a particularly simple and eflicient means for holding the sash weather tight and against rattling,

whichmeans is housed within the sash.

;.The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings, in which like characters designate corresponding parts in all the views. V

This window construction-comprises generally,

a window frame having an inwardly extending guide ribs on one or more members thereof, as on each of its upright sides, a sash having one or more of its members, as each of its stiles,

and/or the bottom rail, formed with a channel,

opening through its edge for receiving the rib, an insert in each channel for thrusting against the rib therein, and means tending to thrust the insert against the rib. The insert has a projec-.

tion coacting with the inner edge of the rib, the projection and the rib having means which act on each other inclined plane fashion to thrust the sash bodily in one direction against the rib and hence, tighten the sash against air drafts and rattling. Usually, the rib isprovided with its inner edge beveled, and the insert thrusts against thebeveled edge. 4

Also, the invention includesa sash holder, or latch, acting inclined plane fashion on the rib to thrust the sash in the same direction as it is thrust by the coaction of the insert and the rib.

1 designates awindow frame having an inwardly projecting guide rib 2 for the window sash 3. The rib here shown is formed up'of sheet metal having base flanges 4 overlying the window frame and secured thereto inany suit able manner, as by screws5. There is a guide rib extending along each upright side of the window frame for coacting with the stiles of the sash, and also if desired, along the sill of the window frame for coacting with the bottom rail of the sash. The sash isformed with a channel opening through each edgethereof for receiving the rib 2, and usually, because a particularly strong, light and compact sash is desirable, the sash isformed up of sheet metal to have front and rear walls 6, '7, a reentrant groove 8 for receiving the pane 9, the. front and rear walls forming the sidesof a channel, which opens thgoigh the edge of the sash for receiving the r1 V a 10 designates one. of the inserts extending lengthwise of each stile,'and in some instances, lengthwise of ,the bottom rail. One or more'inserts maybe located in'each channel. In sash members of comparatively short height or length,

one insert is used.. In longer. sash members, a

the inner edge of each rib is formed beveled, as

at 11, and theinsert is provided with a projection or strip arranged edgewise tothe beveled edge, and coacting therewith; The insert is here shown in the form of a. channeL'U-Shaped in general form, with the side flanges of the U 'for-,

mation located adjacentthe inner faces of the front and rear walls 6, '7 of the sash, the inter mediate part of the U formation being provided with a projectingflange l2'preferably extending parallel to the plane of the sash, the endof which projecting flange coacts with the beveled edge 11 of the rib 2. The channel insert 10 is inserted and removed by an'endwiseactio'n, and the side flanges of the U formation are slidably inter locked with the front and rear walls 6, '7.

As here illustrated, the front and rear walls are provided with inturned marginal flanges 13 opposed to and spaced apartfrom the major parts of the front and rear walls'6, 7, and the side flanges of the insert 10 extend into the spaces between the flanges 13 andthe major portions of the front and rear walls 6, 7. i The inserts are thrust outwardly to cause th projection l2'to-thrust against the beveled edge 11 at all times, and as here illustrated, the insert 10 is carried by a leaf, or bow spring '14 located inthe sash member and thrusting with its ends against the outer side of the bottom of the re entrant channel 8, and-carrying the insert at its apex portion. The spring is held from undue dis-- placement in any suitable manner, as by shoulders 16 punched out from the bottom of the channel 8, and by other inserts, as corner inserts.

Any number of inserts may be used, depending on the length of the stile.

' by rivets 18.

conditions.

19 designates corner inserts at the uppercorners of the sash, these beingusually permanently secured in position as by indenting as at 20, or compressing the side walls of the glass receiving channel 8 onto flanges of the insert, or'compressing the flanges of the inserts between-the walls of the reentrant channel 8, and the'front and rear walls of the sash. This manner of permanently securing'the corner inserts in position, forms no part of this invention.

21 are corner inserts locatedatthe lower corners of the sash and the arm thereof in the bot-' tom rail of the sash carrying latch mechanism including a sliding bolt 22, which is operated by a finger lever 23. This corner iron 21 is removable with the bottom rail from the stiles, for the 1 purpose of removing and replacing a broken glass, and is secured in the stile by removable fastening members, as screws 24.

The sliding bolt isbeveled,'as shown in Figure 5, and coacts with beveled notches 25 in the rib 2, and acts incline plane fashion to thrust the sash in the same direction as it is thrust by the coaction of the rib, and the projection or flange 12 of the insert 10.. The construction of the sash holder, or latch, forms no part of this invention.

- In Figures 4 and 6, the sill of the window frame is shown as formed witha rib'30 corresponding to the rib 2, and the bottom rail is provided with an insert 31 corresponding to the insert 10, and having a flange 32 coacting with the beveled edge 33 of the rib, so that, therib 30 along the bottom railserves asa weather strip, and the insert acts to hold the'sash tight along the ribon the rail.

'In operation, duringraising and lowering of the sash, the inserts 10 slide along the rib, and owing to the fact that the ribs are beveledat their edges, thev sash is pressed inone directionat aright angle ,to its plane and thus held tight under all Also, owing to the rib 30 and the in-. sert 31, the sash is held tight against the rib 30 on the sill when the sashisclosed. Also, the

7 locking bolt 22 acts on the ribs 2'in conjunction with the inserts 10 tohold the sash tight against rattling.
